These might be the secondary reasons but there is something with the genes prior to birth which determines whether a child would grow up to become a right-handed or left-handed person.

The predominant left half of the brain,which graciously supplies the right half of the body,theoretically renders it more skillful in reading,writing,speaking,and working and makes most people right handed.''lefties'' however are the product of an inversion,whereas the right half of the brain predominates,and they work best with the left side of their bodies.
Theory number 2 trickles down to the asymmetrical nature of the body.examples of the asymmetry,which flows from head to the toe,are that the right side of our faces differs slightly from the left,that our legs differ in strength or that our feet vary in size.one aspect of asymmetry is that for most people right hand is stronger than the left.

This seems to be an agreeable answer of the above question.

I think it would be an altruistic statement to assert this. If it was so, many people in the field of physiology would have attempted to find a deliberate way to become left-handed. Still, it's quite predominant to say that left-handed people possess higher problem solving skills. Though, exceptions are everywhere.

I think left-handed people use their right hand just like right-handed people in everything except writing. All the objects mentioned above can still work in the same if operated by a left-handed person. There isn't prejudicial element in it.

Ohh dear Gul, let me give you a happy news! FPSC does offer chairs with arms on their left side for CSS candidates at their headquarters. If you are lucky enough to get your exam center at FPSC Headquarters (F-5 Agha Khan Road, Near Marriott), you will save yourself of some discomfort.
